+Subject: [PATCH] mtd: nand: add Winbond manufacturer and chip
+
+This patch adds the W25N01GV NAND to the table of
+known devices. Without this patch the device gets detected:
+
+nand: device found, Manufacturer ID: 0xef, Chip ID: 0xaa
+nand: Unknown NAND 256MiB 1,8V 8-bit
+nand: 256 MiB, SLC, erase size: 64 KiB, page size: 1024, OOB size : 16
+
+Whereas the u-boot identifies it as:
+spi_nand: spi_nand_flash_probe SF NAND ID 00:ef:aa:21
+SF: Detected W25N01GV with page size 2 KiB, total 128 MiB
+
+Due to the page size discrepancy, it's impossible to attach
+ubi volumes on the device.
